Trying to get spot lock on the ghost to work. I followed instructions on lowrance website how to do it and still won't work. Said to hold 2nd and 3rd button to activate configuration mode. Then push 3rd button until beeps. Then make a slow 360 degree turn until it beeps. Then hold 2nd and 3rd button to exit configuration mode. Did all that and still nothing. I'll hit spot lock and it'll start turning circles and then just take off in some random direction
